Energy is absorbed in discrete amounts. Calculate the wavelength of radiation absorbed during the ionization of an electron from the n = 1 energy level of hydrogen. (Hint: on the Energy Levels For Hydrogen chart, how much energy is required to ionize an n = 1 electron?) Keep 3 significant figures in each of your sub answers and in your final answer as you work through this problem.

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
